Why Can’t I Sleep? The Truth About Hormone Cycling and Insomnia

You’re doing everything right.

You ate a nourishing, mineral-rich meal.

You unplugged early. You skipped the wine. You even lit a candle and made peace with your to-do list.

And yet…

There you are, at 3 a.m., staring at the ceiling, mind racing, sleep nowhere to be found.

And it keeps happening—like clockwork—right before your period.

This isn’t random. And no, it’s not just stress.

It’s hormonal. It’s physiological.

And it’s more common than most practitioners are taught to acknowledge.

The Rhythm Beneath It All

Your hormones are designed to ebb and flow throughout the month. In the first half of your cycle—what we call the follicular phase—estrogen rises. Most women feel energized, productive, even clear-headed here. Sleep often comes easy.

But after ovulation, the terrain shifts.

Progesterone becomes the dominant hormone. It’s meant to be your calming support—your internal exhale. It helps prepare the body for potential pregnancy, but also regulates temperature, sleep, and the nervous system.

When progesterone is low, drops too fast, or isn’t balanced with the rest of your mineral and stress profile, your nervous system doesn’t get the memo to rest.

Instead, it revs.

This is why that classic “I’m tired but wired” feeling shows up. You’re exhausted, but your brain won’t quiet down. You may fall asleep, but wake up at 2 or 3 a.m. with a racing mind or a pounding heart. Or maybe you can’t even fall asleep at all.

It’s Not All in Your Head—It’s in Your Chemistry

Here’s what’s happening under the surface:

As progesterone drops, cortisol often rises. Your stress hormones step in to compensate, keeping you alert when your body is begging for rest.

Melatonin—the hormone that lulls you into deep sleep—gets disrupted. It may come on too late, not enough, or get drowned out by the noise of adrenaline.

And if your mineral reserves are low? It’s even harder.

Magnesium, potassium, calcium—all play a role in calming the nervous system and modulating hormone function. If your system is depleted (which we often confirm through HTMA testing), even the most perfect nighttime routine won’t override the internal imbalance.

But What If It Doesn’t Stop When Your Period Starts?

Here’s the part that surprises most people:

Even once bleeding begins, sleep doesn’t always return right away.

And there’s a reason for that, too.

Once your cycle starts, hormone levels hit their lowest point—both estrogen and progesterone bottom out. Your body is in a state of depletion and repair.

If you were already low in minerals, stressed, or inflamed leading up to your bleed, your system may be working overtime to reset—and sleep takes a back seat.

Many women also experience heightened inflammation around the start of their cycle. Prostaglandins (the compounds that cause uterine cramping) can increase systemic inflammation, which in turn affects the nervous system, digestion, and—yes—sleep.

If you’re bleeding, cramping, and still wide awake at 3 a.m., it’s not because your body is broken. It’s because it’s trying to do a very demanding job with low resources—and it needs rest it can’t quite access.

Sometimes sleep doesn’t return until estrogen begins to gently rise again, around days 3 to 5. That’s when the fog lifts. That’s when the nervous system can start to settle again—if we’ve supported it.

What You’re Feeling Is Valid

This isn’t just about your hormones. It’s about how your body feels safe—or doesn’t.

If you’re waking up in the middle of the night, it might not just be insomnia.

It might be your body saying,

“I don’t feel regulated. I don’t feel safe. I need more support.”

This is where we stop blaming ourselves and start asking better questions.

What’s my body trying to say?

Where am I overextending?

What am I missing—not just emotionally, but nutritionally and hormonally?

So, How Do We Reclaim Sleep?

We begin by listening.

Not rushing to fix, not overriding symptoms—but honoring them.

We support progesterone naturally. We nourish the adrenals. We rebuild minerals.

We lean on plants—reishi, passionflower, chamomile.

We create rhythms that feel like home again.

And we remember that our cycles are sacred, not symptoms to shut down.

This is what real hormone work looks like. Not quick fixes—but deep remembering.

If sleep disappears like a ghost the week before your period, and doesn’t return right when bleeding starts—it’s not in your head. It’s in your hormones, your minerals, your stress patterns.

And the good news? There’s a path back to rest, rhythm, and regulation.
